D 9.89 Consider a current-mirror-loaded differential amplifier such as that shown in Fig. 9.31(a) with the bias current source implemented with the modified Wilson mirror of Fig. P9.89 with I = 200 µA. The transistors have |Vt| = 0.4V and k’W/L = 5mA/V2. What is the lowest value of the total power supply (VDD + VSS) that allows each transistor to operate with |VDS | ≥ | VGS|?
